Three-Quarters of Earth's Land is Drying Out, 'Redefining Life on Earth'
2024-12-25
New research reveals that 77% of Earth's land has become drier over the past three decades, with a rapid increase in excessively salty soils. Climate change is accelerating this trend, expanding drylands to encompass over 40% of the planet (excluding Antarctica). This threatens agricultural productivity, biodiversity, and ecosystem health, exacerbating food and water insecurity. Unless emissions are curbed, this trend will continue, leading to severe socioeconomic consequences including hunger, displacement, and economic decline. Experts urge immediate action, including investments in drought-resistant and salt-tolerant crops, improved crop and water management, and nature-based solutions.
